J., .assigner to Art Metal Works,` Inc., Newark, N. J., acorporation of New Jersey Application January 31, 1931. Serial No.512,614 9 Claims. (Cl. 30-1Z) This invention relates to a combinedsafety razor and sharpening mechanism.

Among the objects of this invention is the pro- Vision of a safety razorincluding a sharpening device, together with means providing convenientmeans for turning of the blade, if adouble edged blade is used, ktopresent either of its edges to the sharpening device or to the shavingposition'without removing the blade from its clamping means. f

The invention consists in such novel features, arrangements andcombinations of parts, as may be shown, described and claimed inconnection with the embodiments of the invention herein disclosed by Wayof example only.'

Other objects of the invention will be apparent from the followingdescription taken in connection with the drawing, in which Fig. 1 is acentral longitudinal sectionv of a combined safety razor and sharpeningmeans Fig. V2 is a section similar to that in Fig. lshowing o ne edge ofthe blade in shaving position and the Yother edge in sharpeningposition; t

Fig. 3 is a longitudinal section" through the head of the razor when theparts are in the position shown in Fig. 2;

Fig. 4 is a top view of the Yguard and sharpening device;

Fig. 5 is a top View of Figs. 1 and 2;

Fig.'6 shows a modiiication; and

Fig. 7 shows still another modification.

The invention shown in Figs. 1, 2, 3, 4 and 5 includes a hollow handle10 to which a supporting member 11 is suitably secured or formedinporting member 11 is a guard 12 which may be constructed as shown, andmay be provided with v vbecomes dull the blade may be moved from thevtwo spacing lugs for spacing the razorfblade 14 from the guard 12 so asto provide anpopening between the blade and the guard'through whichlather and hair cuttings may pass to facilitate the cutting operationofthe blade. l l

The blade 14 may rest'onian V*inner seat 'or clamping member or plate15' which'is connected by means of a flexible connection l'with aistem17 extending through the hollow handle 10, as indicated in'Figs. land 2.This stem 17 may be held against rotation in the handle 10 by means of apin 18 operating in a slot in the handle, as

shown.

The clamping member 15, vas shown^ in Fig. 3, carries a pair of aligningpins 20 which when the blade 14 is moved toward operating positionengage in holes in the supporting member 11 to` -in the handle 10 and atits other end against shortl as well as the. stem 17a, while the cap 26amay be made relatively long andmay constitute i align the edges of theblade with respect to the 1' guard 12 and the sharpening means 21 which,as shown in Fig. 1, may be in the form of a roller constructed of anysuitable material such as glass, chromium plated metallic cylinders, orany cylinders having glazed or enameled surfaces or cylinders of anyotherl suitable material. The sharpening roller is supported on ears 22preferably integral with the supporting member 11. The roller may berotated by rolling the same over the hand of the user or otherwise asdesired. For the purpose of drawing and retaining the blade in operativeposition, a spring 25 is provided bearing at onek end against a shoulderwiththe end` of a cap 26 having a screw connection with the stem 17. Thenecessary tension of the spring 25 may be obtained by turning the cap 26on the stem 17 until its movement is limited by a stud 27 threaded inthe closed end of the cap, as shown. Preferably, this adjustment is madei at the factory but if any adjustment is needed later on it may readilybe effected by a change in the position of the stud 27.

The aligning pins 20 are preferably formed ywith enlargedaligning'portions 30 which flt in and extend through a slot in the razorblade and are adapted to be engaged by an outer clamping gember or plate'31, after this has been placed in position under the heads 32 of thealigned pins 20. The'clamping plate 31 is provided with a grippingsurface 33 to facilitate the removal of the plate from, or itsconnection with, the heads of the aligningA pins 20. The construction issuch that when the removable clamping plate is in position, the razorblade 14 will be under the re-l quired tension.

When the edge of the blade in shaving position operative position shownin Fig. 2 to the position pins are disengaged from the supporting member11 and the clampingplates and the razor blade are yfree to be turned topresent the other or sharpened edge into shaving position and to presentthe dull edge into position to be sharpened by the roller 21.

' As shownin Fig. 7, the portion corresponding to the handle 10,'shownat 10a, may be made the handle proper. By means of this construction itis possible to disconnect the handle from the razor for convenience inYpacking.

The operation of the stems 17 and 17a is 110 facilitated by means ofengaging ilanges on the handles l0 and 10a and the caps 26 and 26a.

In the modification shown in Fig. 6, the inner clamping member or plate15b is supported on a hollow stem 17h and the outer clamping member orplate 31h is supported on a stem 35 which extends through the stern 17D,the stems being moved relatively longitudinally to move the clampingplates 15b and 31h to clamp or free the razor blade, by means of a cap26h which bears against a spring 25h which in turn, bears against ashoulder within the handle 10b.

By means of this construction the razor blade may be removed from therazor by removal of the cap 26h which permits the clamping plate 31h tobe removed. By pressing on the cap 26h the razor blade may be moved intothe position shown in Fig. 1 in connection with the operation of themodication shown in Fig. 2, and by turning the cap 2Gb the blade may berotated to present its dull edge to the sharpening device and its sharpedge to the guard as may be readily understood.

YWhile the invention has been described with respect to certainparticular preferred examples which give satisfactory results, it willbe understood Aby those skilled in the art, after understanding theinvention, that various changes and modications may be made withoutdeparting from the spirit and scope of the invention, and it isintended, therefore, Vin the appended claims to cover all such changesand modifications.
